Device for clamping thick, textured or coily hair

ABSTRACT

A device for clamping thick, textured, coiled or kinky hair includes first and second curved components, each with an outer edge and an inner concave curved edge between first and second ends. The inner concave edges include a plurality of inwardly directed, spaced-apart teeth. A hinge joins the first ends of the curved components, enabling the second ends of the components to open and close around a bundle of hair with the teeth penetrating into the bundle. A cooperating closure maintains the device in position around the bundle of hair. The ends of the teeth define an opening even when the device is closed around the bundle of hair. The first and second curved components are preferably integrally formed from molded plastic. The cooperating closure may include first and second hook shapes. The device may come in different sizes to accommodate different hair textures and styles of children and adults.

FIELD OF THE INVENTION

This invention relates generally to hair accessories and, in particular, to a hair clip for thick, textured or coily hair.

BACKGROUND OF THE INVENTION

Most hair styling accessories are designed for straight hair, and they cannot accommodate thick textured or coily hair. Hair ties, including “scrunchies,” are difficult to get around and remove from thick gatherings of textured hair, and since the teeth of “banana clips” overlap, the jaws are too small. Again, banana clips are really intended for straight hair.

SUMMARY OF THE INVENTION

This invention resides in a sanitary, durable and affordable device that clamps thick, textured, coiled or kinky hair without over-squeezing. The device includes first and second curved components, each component having an outer edge and an inner concave curved edge between first and second ends. The inner concave edge of each component includes a plurality of inwardly directed, spaced-apart teeth. A hinge joins the first ends of the curved components, enabling the second ends of the components to open and close around a bundle of hair with the teeth penetrating into the bundle.

A cooperating closure associated with the second ends of the components is used to maintain the device in position around the bundle of hair. In contrast to existing devices, the teeth of one component never touch or bypass the teeth of the other component. Rather, the ends of the teeth define an opening even when the device is closed around the bundle of hair. In the preferred embodiment, the ends of the teeth define a biconvex opening when the device is closed around the bundle of hair.

The first and second curved components are preferably integrally formed from molded plastic, for example. The cooperating closure may include first and second hook shapes on the second ends of the first and second curved components. The device may come in different sizes to accommodate different hair textures and styles of children and adults. For instance, the outer edges of the first and second may define a diameter or dimension in the range of 1 to 5 inches. The length of the teeth may vary from shorter near the ends of the components to longer in the middle, and the outer edges of the first and second curved components may define substantially smooth convex curves.

DETAILED DESCRIPTION OF THE INVENTION

The drawings present different views of the preferred embodiment of the invention. FIG. 1 is an oblique view of the device in a closed position. The device comprises a first curved component 102 and a second curved component 104 connected with a hinge 106, allowing the opposing ends to open and close like jaws. The components are preferably made from a rigid or semi-rigid durable material such as ABS, nylon or other plastics, through materials such as wood or metals may be used. In the preferred embodiment, each component is a unitary structure made from integrally molded plastic, for example, with a plastic or metal rivet being used for hinge 106. The device may come in different sizes, with the dimension “D” in FIG. 3 being in the range of 1.5 to 5 inches to accommodate children and adults with different hair styles and textures. For example, devices with outer sizes of 1.5″, 2.25″, 3.5″ and 5″ may be provided. The device may be made in any color(s), including colors to blend in with hair colors or contrast with typical hair colors.

Component 102 includes an outer edge 101 and an inner edge 103 from which there projects a plurality of spaced-apart inwardly directed teeth 112 with tips 114. Likewise, component 104 includes an outer edge 105 and an inner edge 107 from which there projects a plurality of spaced-apart inwardly directed teeth 116 with tips 118. In contrast to existing hair clamps, including the “banana clip,” the teeth 112 or tips 114 of component 102 never touch or bypass the teeth 116 or tips 118 of component 104. Rather, even when the device is closed, the tips of both sets of teeth leave a central opening 202 shown in FIG. 2 to better accommodate a gathering of thick, textured or coily hair. In the preferred embodiment, this opening approximates a bi-convex shape shown with broken lines 204. The teeth are preferably angled so as to project generally radially inwardly toward the center of opening 202, with the length of the teeth being graduated from longer teeth 206, 208 near the middle of the device to shorter teeth 210, 212 toward the ends. The teeth may have lengths in the range of ¼ inch or less, to 1 inch or more, depending upon the outer dimension “D.”

At the end of the device opposite the hinge 106, a closure mechanism is provided to keep the device in place around a gathering of hair. In the preferred embodiment, component 102 includes a C-shaped hook of material 110 that engages with a corresponding C-shaped hook of material 108 on component 104 as shown in FIGS. 1, 2 and 4-8. As best seen in FIGS. 5-8, the components and teeth are preferably angled to approximate a frustoconical form 702 terminating in point 704. As evident form the figures, the two components 102, 104 are nearly minor images of one another, with slight differences around the hinge and closure to better maintain a flat front plane 706.

To use the device, hair is gathered with the hand(s) of the user to create a bundle to be clamped. The device is opened more than that shown in FIG. 3. With the bundle of hair maintained with one hand, the opened device is placed around the bundle with the other, at which point both hands may be used to close the device around the bundled. The device is initially is “over-closed” so that the ends 109, 111 of the hooks 108, 110 in FIG. 1 engage, enabling the device to be left in place. In the preferred embodiment, flat plane 706 is oriented toward the head of the wearer with the point 704 of the conical shape pointing backward so that the device essentially “cups” the back of the head to be less conspicuous.
